steps of body response to water deprivation

1) dehydrated, loss of water, lead to an increase in osmolarity 2) osmoreceptors are activated in the hypothalamus, it stimulates thirst, and stimulate the secretion of ADH from the pituitary gland 3)ADH leads to an increase in H20 permeability in the principal cells of the late distal tubule and collecting duct 4) increase water permeability -> increased reabsorption of water 5) as more water is reabsorbed, urine osmolarity decrease, and urine volume decreases 6) since more water is reabsorbed, plasma water increases, osmolarity decreases in plasma, and return to normal

steps of body response to drinking water

1) drink water, decrease plasma osmolarity 2) inhibit osmoreceptor in the hypothalamus -> decrease thirst response -> inhibit ADH secretion 3) as a result of less ADH, there is a decrease in water permeability of the late distal tubule and collecting duct 4) decrease in water permeability, decrease in water reabsorption, 5) water that is not reabsorbed is excreted -> decrease urine osmolarity -> increase urine volume 6) -> Because less water is reabsorbed, less water is returned to the circulation. Coupled with the inhibition of thirst and the suppression of water drinking, plasma osmolarity increases back toward the normal value.

How are fat soluble vitamins absorbed?

Fat-soluble vitamins dissolve directly into chylomicrons to enter the lymphatic circulation

intimacy vs isolation

Favorable outcomes are love, the ability to have intimate relationships with others, and the ability to commit oneself to another person and to one's own goals. If this crisis is not favorably resolved, there will be an avoidance of commitment, alienation, and distancing of oneself from others and one's ideals. Isolated individuals are either withdrawn or capable of only superficial relationships with others

initiative vs guilt

Favorable outcomes include a sense of purpose, the ability to initiate activities, and the ability to enjoy accomplishment. If guilt wins out, the child will be so overcome by the fear of punishment that the child may either unduly restrict himself or may overcompensate by showing off.

For adolescents, this can expand to social circles, including friends, peers, and teachers.

Each of the following theorists (Freud, Erikson, Kohlberg) evaluates an individual and determines that the person has failed in completing one of the theorist's developmental stages. What would each say is the most likely outcome for this person?

Freud would say that the individual has become fixated in that stage and will display the personality traits of that fixation for the rest of his or her life. Erikson would say that the individual will still move through subsequent phases, but will be lacking the skills and virtues granted by successful resolution of that stage. Kohlberg would say that the individual was incapable of reasoning at the level of failure and that the individual would use the reasoning described in previous stages to resolve moral dilemmas.

how does norepinephrine and epinephrine affect the heart ?

Norepinephrine from sympathetic neurons or epinephrine from the adrenal medulla binds to adrenergic receptors in the heart, causing an increased heart rate and greater contractility

example of sensory bias

For example, fiddler crabs are naturally attracted to structures that break up the level horizon because they may indicate a food source; male crabs take advantage of this fact by building pillars around their territory to attract mates.

Integrity vs. Despair

If favorably resolved, we will see wisdom, which Erikson defined as a detached concern with life itself, with assurance in the meaning of life, dignity, and an acceptance of the fact that one's life has been worthwhile, along with a readiness to face death. If not resolved favorably, there will be feelings of bitterness about one's life, a feeling that life has been worthless, and at the same time, fear over one's own impending death

Trust vs. Mistrust

If resolved successfully, the child will come to trust his environment as well as himself. If mistrust wins out, the child will often be suspicious of the world, possibly throughout his life.

impression management

Impression management refers to our attempts to influence how others perceive us. This is done through the regulation or controlling of information in social interactions

what is the premise of Kohlberg's theory on personality development?

Kohlberg's theory of personality development focuses not on resolving conflicts or urges, but rather on the development of moral thinking. Kohlberg reasoned that, as our cognitive abilities grow, we are able to think about the world in more complex and nuanced ways, and this directly affects the ways in which we resolve moral dilemmas and perceive the notion of right and wrong

in fasting state, what happens to beta-oxidation ?

In a fasting state, the liver produces more acetyl-CoA from β-oxidation than is used in the citric acid cycle. Much of the acetyl-CoA is used to synthesize ketone bodies (essentially two acetyl-CoA molecules linked together) that are released into the bloodstream and transported to other tissues.

In some complexes, the central cation can be bonded to the same ligand in multiple places. This is called chelation, and it generally requires large organic ligands that can double back to form a second (or even third) bond with the central cation.

how is glomerulotubular balance maintained ?

In summary, increases in GFR produce increases in the filtration fraction, which leads to increased πc and increased reabsorption in the proximal tubule; decreases in GFR produce decreases in the filtration fraction, which leads to decreased πc and decreased reabsorption. The proportionality of filtration and proximal tubule reabsorption is thereby maintained (i.e., there is glomerulotubular balance).

The combined mechanical and chemical digestive activities of the stomach result in a significant increase in the surface area of the now unrecognizable food particles, so when the chyme reaches the small intestine, the absorption of nutrients from it can be maximized

explain the common ion effect

The common ion effect is really Le Châtelier's principle in action. Because the solution already contains one of the constituent ions from the products side of the dissociation equilibrium, the system will shift toward the left side, reforming the solid salt. As a result, molar solubility for the solid is reduced, and less of the solid dissolves in the solution—although the Ksp remains constant.

The descending limb of the loop of Henle is permeable to water but not salt; therefore, as the filtrate moves into the more osmotically concentrated renal medulla, water is reabsorbed from the filtrate

the disease tetanus

The disease tetanus is caused by a bacterium called Clostridium tetani that releases the toxin tetanospasmin. Tetanospasmin blocks the release of GABA from the neurons that inhibit motor neurons, making the motor neurons overexcitable. This leads to constant contraction of muscles, which can be so strong as to fracture bones

example of exothermic solvation

The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapor pressure at normal temperatures is often referred to as volatile. The pressure exhibited by vapor present above a liquid surface is known as vapor pressure. As the temperature of liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.
